Question

when objects move along fixed circular paths, like a wheel on a bicycle spinning around a fixed axis. in these instances, different forces act on objects, moving them differently. which term matches the picture? rectilinear motion simple harmonic motion rotary motion

Explanation:

Rectilinear motion is motion along a straight line. The train in the picture is moving along a straight - like elevated track, which fits the definition of rectilinear motion. Simple harmonic motion is a periodic motion where the restoring force is proportional to the displacement (e.g., a pendulum). Rotary motion is circular motion around an axis (like a spinning wheel). Since the train is not moving in a circular path (rotary) or a periodic back - and - forth (simple harmonic), rectilinear is the correct term.

Answer:

rectilinear motion
